Title: Product-sum arithmetic circuit
Inventor: KOTOBUKI KOKURIYOU
IPC: G06J1/00
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To attain the product-sum operation of digital multipliers corresponding to plural analog voltage values by the comparatively small number of capacitance elements by adding bits corresponding to the multipliers of plural data and then weighting the added result in accordance with the weight values of respective bits. SOLUTION: An addition part ADD is connected to a sample and hold part SH to which analog input voltage Vin is inputted, plural analog voltage values stored in the sample and hold part SH are mutually added and the added result is multiplied in a multiplication part MUL. A control signal CTRL1 is inputted from a multiplier control circuit CTRL to the sample and hold part SH and a control signal CTRL2 is inputted to the addition part ADD. Thus the corresponding bits of multipliers of plural data are mutually added at first, and then the added result is weighted in accordance with the weight values of respective bits. When multipliers are circulated, transfer errors can be suppressed.

Filed: 1992-11-05
Abstract: PURPOSE:To simplify the operation of a corrected value storage, and to obtain an exact measured value even when a variation is generated among products by providing an automatic corrected value calculating means and a corrected value storage means. CONSTITUTION:For example, an IF(intermediate frequency signal) level monitor circuit of a modulating unit(NOD) 40 is equipped with a level detecting circuit constituted of a detector 30 and a multiplier 32, A/D converter 48, CPU 50, and E<2>PROM 52. The CPU 50 transmits an instruction to set the frequency of an outside oscillator 64 at a prescribed intermediate frequency, gradually changes an output level, and inputs data from the A/D converter 48. The CPU 50 discriminates whether or not the inputted data are matched with a designed value within a prescribed permitted range. Then, when the inputted data are not matched with the designed data, the CPU 50 prepares a conversion table, and writes it in the E<2>PROM 52. When the inputted data are matched with the designed data, the CPU 50 writes a flag to indicate that the correction s not necessary in the E<2>PROM 52.

Title: Time-out detecting system
Inventor: SUGIYAMA YUKINORI
IPC: G06F13/00
Filed: 1988-11-22
Abstract: PURPOSE:To quickly execute the detection of time-out from hang-up without containing the information transfer time by loading a value to a timer circuit, whenever an REQ signal and an ACK signal for controlling an information transfer is sent out. CONSTITUTION:When hang-up does not occur in the course of information transfer and handshake is executed smoothly, a signal 106 does not become active, but when sending-out of one signal stops, a pulse is not generated in a load signal 104, a timer circuit becomes time-out and the signal 106 becomes active. Accordingly, by monitoring the signal 106 in the course of information transfer, time-out can be detected. Also, according to this system, whenever an REQ signal and an ACK signal rise, a value is loaded to the timer, therefore, its load value can be determined from only a time-out decision time irrespective of the time required for the information transfer.

Abstract: PURPOSE:To secure safety of an operation and to improve the processing accuracy of a product by rotating a work around its axis through a process of rotating and driving a constraining means, and providing a rotational driving mechanism for positioning the grinding surface of a work in relation to a grinding wheel. CONSTITUTION:A spindle head 5 is once raised after finishing the grinding of one surface of a workpiece W, and an attitude is changed so that a surface next to that previously ground may be faced to a grind wheel 6.
